To all whom `it may concern:

Be it known that I, GEORGE MGMULLEN, a-

' subject of the King of Great Britain and Ireland, resid ing at Sampsons Buildings, Barrack street, Perth, Western Australia, Australia, have invented a certain new and useful Im-` provement in Collapsible'Blinds or Shutters, of which the following is a specification.

This invention relates to lathblinds andi shutters, and more particularly to that kind of blind usually fitted in tram and railway .l so

cars and such like vehicles for intercepting "ithesrays o f the sun and alsoallowing the air to passV freely through the car, such blinds acting as auxiliaries for the ordinary glass windows.

According to this invention the laths or slats 'which compose the shutter are formed at the center of their ends with projecting studs, and on both sides of such studs pins are provided.

These studs run freely in grooved bars fittedon each side of the shutter, and in the case of an ordinary window these grooved bars may be attached to the inside face of the window frame. Instead of forming the studs and piv-Y ots in one piece with the slats the slats may be incased at their ends by metal caps, which t over the ends and which may be kept in place by pins or otherwise., These caps are formed on the outside with the studs and pins. Short strips of metal acting as links for connecting the slats together are pi'voted at the center of each cap by the studs before mentioned and attached by the pins to alternate ends of each adjacent slat, the studs acting as the pivots for the links. These links are interposed between the ends of the slats and th grooved bars forming the guides.

In the accompanying drawings, Figure l is a front face view of a blind constructed accor-ding to this invention and as seen from the inside of the window. Fig. 2 is a similar view with the slats in the raised position, as when notin use. Fig. 3 is an end View looking to- .ward the right with thel left side guide reeral surface of the Slat formed with the stud and hinge. Fig. 6 shows one end of a slat ncased in 'a cap which is provided withfthel stud and pins.

In Figs. l to 5 of the drawings, a are the slats i which make up the blind and which are'made one with the studs, as c, at about the center of their ends and also with the pins, as d.

The links', as e, areheld loosely on the slats by the studs and at their extremities are con. nected to the upper and lower slats by the pins, as shown. The heads of these pins may be riveted and countersunk. The studsc move vand work freely in the grooves of the bars f,

as shown. These guides are secured to the inside edge of the window-frame j.

Inthe type of slat as shown in Fig. 6 the ends are ineased by metal caps :,`Which lit over such ends and 'may be kept in place' by pin'sor otherwise. These caps are formed on the outside with .the projecting studs c and pins d. i

The'upperrnost or any slatf'may be secured from moving along the guides by havingr its studs pivotally fixed to the frame.

In the blind as illustrated the studs of the top Slat are held tothe window-frame, and therefore carry all the slats of the blind, which when'not in useE forms a compact body at the the slats, but may be formed only oneach alternate one, or, in the case of agreater number of slats, on every third, fourth, or any one. I n such case' pins similar to the outer ones would act as the pivots for the links.

The studs o are enlarged at their outer ends, as shown at the left of Fig. 5, the enlarged portion engaging the window-frame and preventing the removal of the links.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a blind or shutter, the combination with vertical bars ou the sides of a window,

said bars being provided with longitudinal grooves, of slats provided with caps fitting upon and secured to the ends of theslats, said caps each having a central headed stud and a .pin on each side of the stud, ther said studs having their heads working in thegrooves of said bars, and links pivoted at the center of their length on the stud of one Slat between the slat and the head of the stud and having their ends pivoted to the pins of the caps of two adjacent slats, substantially as herein shown and described.

2: In a blind or shutter, the combination of longitudinal grooved bars at the sides of a l 'K Window, of slats provided at the center of their ends with headed studs having their heads engaging the grooves of said bars, said slats being also provided at their'ends adjacent to opposite edges with pins, and iinks pivoted at the center of their length on the stud of one Slat between the slat and the head of the stud, and having their ends pivoted to hand in presence of two witnesses. l
